Synthesis Technology E580 Mini Delay

The E580 emulates the classic sounds of digital, BBD (bucket brigade), and tape-based delays with four parameters under voltage control.

This 14hp wide Eurorack module accepts either +/-12V standard power or +/-15V MOTM/power. Using a 40MHz DSP and 24-bit codec, the E580 recreates the pitch-shift modulation of BBDs, including the variable bandwidth and noise floor, without costly and scarce BBD ICs.

In Tape Mode, wow & flutter, tape saturation and non-linear distortions emulate classic tape units without the bulk and maintenance. There are two simultaneous audio outputs: a straight delay and a variable tapped delay.

The tap position is a percentage of the main delay time. This allows very short delays (<350?s) as well as long delays (750ms).

Both tap position offset and main delay time are voltage-controlled over a -5v to +5v range.

Feedback is jumper-selectable from either the tapped position or the main delay. This flexibility can generate standard rhythmic delays (feedback from main delay) or a series of pre-delay reflections (tapped delay) which sound very different from each other.
